Remote MCP Server (Authless Cloudflare)

This MCP server lets you run a remote MCP instance on Cloudflare Workers that serves tools over an SSE endpoint. You can connect from built-in MCP clients or from your own local clients, enabling you to run tools remotely while keeping the execution isolated in a scalable edge environment.

How to use

Once your MCP server is deployed, you can access it from MCP clients to run your tools. Use the remote endpoint to link with cloud-based or local clients, then invoke tools as if they were running locally.

How to install

Prerequisites you need before starting:

• Node.js installed (version 14+ recommended)
• npm or yarn for package management

Create and deploy the remote MCP server to Cloudflare using the following command. This will set up a remote MCP server accessible at a Cloudflare Workers URL.

Install commands

npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless

Notes on deployment options

You can also start from a Cloudflare deployment URL in your browser to configure and deploy your MCP server quickly. The deployment URL follows the pattern remote-mcp-server-authless.<your-account>.workers.dev/sse.

Additional sections

Customize your MCP server by editing the init() method in src/index.ts and adding your tools with this.server.tool(...). This is how you expose new capabilities to clients.

Connect to Cloudflare AI Playground

From the Cloudflare AI Playground, you can connect to your MCP server as a remote client by entering your deployed server URL, for example remote-mcp-server-authless.<your-account>.workers.dev/sse. This enables you to run your tools directly from the playground.

Connect Claude Desktop to your MCP server

You can also connect to your remote MCP server from Claude Desktop by using the mcp-remote proxy. In Claude Desktop, go to Settings > Developer > Edit Config and update with the following configuration. This enables Claude to discover and run your remote tools.
